Subscribers only
A suspended wooden ring resonates with the wind, anchored by a slanted lava concrete spike that elevates visitors for a panoramic view of Iceland's unique volcanic landscape while serving as a communal observation point.
5 key facts about this project
01
A suspended wooden ring acts as an aeolian harp, creating sound through wind interaction.
02
The observation platform is 18.72 meters high, offering a 360-degree view of the surrounding landscape.
03
Lava concrete is used for the main spike, reflecting local geological characteristics.
04
Post-tensioned cables allow for a stable yet open structure, minimizing visual obstruction.
05
The design encourages visitor engagement with natural elements through sound and scenic views.

The Aeolian Tower is located in the dramatic landscape of Iceland, designed to enhance the visitor experience of its natural surroundings. This structure serves not only as an observation point but also as a means to connect people with the landscape through the medium of sound. Inspired by the concept of an aeolian harp, the design allows the wind to play music while directing attention to the striking geological features nearby.

Structural Design
-
The tower features a slanted concrete spike that rises toward the sky, carefully angled to engage with a nearby fissure. This tilt draws the observer’s gaze upward and establishes a connection to the unique topography of the area. A wooden ring, suspended at the base of the spike, serves as an important part of the aeolian harp. This element allows the wind to generate sound, turning the experience of viewing the landscape into one that also involves listening.

Observation Platform
-
Reaching a height of 18.72 meters, the observation platform offers a panoramic view of significant natural landmarks, including the fissure, Hverfjall volcano, and Lake Mývatn. The circular design can accommodate several visitors at once, allowing for shared moments of reflection while immersed in the natural environment. This connection further enhances the relationship between the structure and the landscape.

Materiality and Construction
-
Lava concrete is used in the construction of the tower, chosen for its ability to combine visual appeal with structural strength. This material reflects the local geological characteristics and contributes to the durability of the design. The wooden ring is suspended from the concrete spike using post-tensioned cables, which help maintain stability while allowing for an open and inviting structure.

Cultural Context
-
The Aeolian Tower integrates historical elements of Icelandic habitation, emphasizing how people have interacted with their environment throughout time. By expertly blending space, sound, and material, the tower offers a rich experience that encourages visitors to engage with the landscape in a meaningful way. The wind vibrates the wooden ring, creating subtle music, reminding all who visit of the lasting interplay between architecture and the natural world.

Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
